One of the espionage things that annoys me is that it's a continual build up. Once you've spent all you can spend.. it's spent.
A counter-espionage option would be nice, especially in the late game when you have several computer players spying on you...
Which means they can steal techs, check out your worlds.. etc..
IT would be nice if you could fund a single pool of counter espionage but have to still parcel out for individual empire espionage.
However, catching a spy is hard work, so $10 BC spent on counter-espionage only counters $1 BC of Espionage (or something of that nature.. probably higher amounts like $20BC to $1 BC when you have all 9 opponents.
So what do you guys think?
